Get a basic idea of how sentences are constructed. This will not be too difficult, as German is very similar to English in this way. There are slight variances but you can learn some now and will learn the more complex ones with time.t is also important to learn some basic words before traveling to Germany or trying to talk to any Germans. 1  Start with important singular words, like âyesâ, ânoâ, âpleaseâ, âthank youâ, and the numbers 1-30. 2  Move on to basics like âI amâ (Ich bin), âYou areâ (Du bist), âHe/She isâ (Er/Sie ist), etc.
A Coefficient is a number used to multiply a variable (4x means 4 times x, so 4 is a coefficient) Variables on their own (without a number next to them) actually have a coefficient of 1 (x is really 1x) Sometimes a coefficient is a letter like a or b instead of a number: Example: ax 2 + bx + c
The kappa statistic (or kappa coefficient) is the most commonly used. statistic for this purpose. A kappa of 1 indicates perfect agreement, whereas a kappa of 0 indicates agree-. ment equivalent to chance. A limitation of kappa is that it is affected by the prevalence of the finding under. observation.
